  Yes, I've created a custom libpython23.a file with
I think impdef or such from the free borland command line
compiler and the dlltools from mingw.
Then I set PYTHON_LIB_PATH to where I stored the libpython23.a
and PYTHON_ROOT to the standard Python directory.
Afterwards I used bjam -sTOOLS=gcc-nocygwin to build the
example supplied with boost python. Since I used cygwin
I had to recompile bjam before boost, because cygwin has
different absolute path names. That's also the reason why
the tests in the example failed. However if you manually
copy the dll-files to the python src directory everything
runs as expected. I've only compiled boost-python and it's
dependencies.
The supplied commands and path-names are recovered from
memory and might be wrong.
A similar route should also work with mingw. I wonder
if there even is a difference between
-mno-cygwin and plain mingw.

Ciao,
